Compact Mini-ITX chassis with GPU headroom

The SilverStone Fortress SST-FTZ01B-E is a Mini-ITX case built around an aluminum unibody frame and steel chassis. It targets builders who want a slim, console-style enclosure that still accepts full-length graphics cards. The design omits a side window for a clean, understated look. Two included 120mm fans provide baseline airflow out of the box.

GPU length and cooler height set the build limits

A graphics card up to 13 inches (330mm) long and 5.88 inches (149mm) wide fits inside, but the CPU cooler cannot exceed 83mm in height. The power supply mount at the rear accepts ATX units up to 150mm long. Only two expansion slots are available, so dual-slot cards consume both. Four internal 2.5-inch drive bays handle SSD storage, while 3.5-inch drives are not supported.

Included 120mm fans define the thermal baseline

Two 120mm fans rated at 1500rpm and 18dBA ship with the case, one mounted at the top and one at the bottom. Additional bottom slots accept a second 120mm fan if extra intake is desired. Front I/O supplies two USB 3.0 ports, audio and microphone jacks. The chassis measures 4.21 by 14.80 by 13.82 inches and weighs 9.26 lbs.

Questions about this item

Should I pick the Mini-DTX or Mini-ITX motherboard option for this Fortress case?

Both Mini-DTX and Mini-ITX boards fit the chassis; choose Mini-DTX only if you need the extra expansion slot that the longer board provides, otherwise Mini-ITX is the standard choice.

What does the 330 mm GPU length limit mean when I install a card?

You can fit graphics cards up to 13 inches long, but the 149 mm width restriction rules out the thickest triple-slot models even if they meet the length figure.

How do the front USB 3.0 ports connect to the motherboard inside the case?

The two USB 3.0 ports route to a standard 19-pin internal header on the motherboard; if your board lacks that header you will need an adapter or a rear-I/O solution.
